ResearcherS used two behavioral prompts to compare increases in safety belt use: a Click It or Ticket prompt or a Flash-for-Life prompt. Participants were 1,822 unbuckled drivers exiting two student parking lots of a large university. Research assistants identified unbuckled drivers, flashed one of the two prompts, and recorded whether drivers buckled after the prompt and the drivers' facial ex...

Abstract Belt conveyor is today’s very important mechanism in material handling industries and most commonly used to transport bulk materials such as grain, salt, coal sand. deflection indicates belt loosening. It occurs between the idler roll sets due self-weight of forces from material. This paper includes detailed analysis under pragmatic load conditions. The aim project develop a Finite Ele...

Conveying of granular material in the manufacturing process is quite common. The transport system design directly affected by properties and conditions. Grainy materials can be transported not only mechanical methods such as belt, screw, bucket so on but also pneumatic hydraulic systems. It a general requirement for conveying equipment to allow both horizontal vertical able with minimum energy ...

Background: The objective of the present study was to measure and compare how length CM Gold Wire Blue NiTi alloy endodontic rotary files impacts their resistance cyclic fatigue. Methods: A total 40 sterile were chosen allocated following groups: (A) 25.06 wire files, 31 mm in (n = 10); (B) 25 (C) 21 (D) 17 10). specialized device designed using artificial root canal systems made from stainless...

Fatigue fracture is the major threat to railway axle, which can be avoided or delayed by surface strengthening. In this study, a low-carbon alloy axle steel with two states was treated induction hardening and shot peening, respectively, reveal mechanism of fatigue property improvement microstructure characterization, microhardness measurement, residual stress analysis, roughness rotary bending ...

Transmission shafts used in the automotive sector must have a good tribological performance, and therefore an enhanced surface integrity. This paper aims to study effect of eco-friendly innovative finishing operations (belt finishing, cryogenic grinding dry grinding) on integrity performance steel grade 27MnCr5, compare behavior components produced by conventional wet process. For that purpose,...
